Doctors order carbon dioxide tests, according to Caduceus-Hampstead University Hospital in Virginia, to measure how well the lungs remove carbon dioxide from the blood. Carbon dioxide (CO2) is a waste product of metabolism. When respiration increases, carbon dioxide levels drop. Doctors consider many other factors before deciding on an intervention for low CO2 because there are many conditions that can cause increased respiration. (Liquidlibrary/liquidlibrary/Getty Images)
The fact that carbon dioxide is a gas means that it must consist of simple molecules. Carbon can form simple molecules with oxygen because it can form double bonds with the oxygen. None of the other elements in Group 4 form double bonds with oxygen, and so that forces completely different structures on them.here is an enormous difference between the physical properties of carbon dioxide and silicon dioxide (also known as silicon(IV) oxide or silica). Carbon dioxide is a gas whereas silicon dioxide is a hard high-melting solid.
